Understanding the Impact of Economic Dispatch on Your Power Bill in West Virginia As reported by West Virginia Public Broadcasting reporter Curtis Tate, a recent story caught my attention regarding a potential settlement between the Sierra Club and the West Virginia Public Service Commission (PSC) over a federal lawsuit. However, what I discovered was more than just a lawsuit—it's about your power bill. In the PJM territorial market, where West Virginia falls, PJM is responsible for coordinating numerous utilities that make up the electric grid system. To grasp the issue at hand, it's essential to understand two key commodities in the wholesale electric market: capacity and energy. Capacity refers to the ability to produce electricity measured in megawatts (MW), while energy is the actual electricity produced, measured in megawatt hours (MWh). Utilities in PJM must meet certain capacity requirements to ensure enough electricity is available during peak demand periods. However, a utility's own capacity may not always be the most cost-effective option for generating electricity. This is where economic dispatch comes into play. Economic dispatch ensures that the lowest-cost capacity is used first to generate electricity, ultimately keeping prices down for utility customers. The problem arises when a regulator, such as the PSC, mandates a fixed capacity factor for a power plant, which can disrupt economic dispatch. If a power company is required to operate a plant a certain percentage of the time, regardless of market economics and pricing signals, that plant may produce electricity at a higher cost than other available sources. In other words, customers could end up paying more for electricity than necessary. The decision to prioritize keeping power plants running, whether fueled by coal, gas, or another source, is a policy decision worth debating. Some may accept the tradeoff to support West Virginia's struggling fossil fuel industries, particularly coal. However, I'm not here to advocate one way or another; my goal is to ensure awareness and understanding. As someone who has spent more than 12 years working for an electric utility, including being a director of federal policy for American Electric Power, my views are personal and do not reflect any other entity's stance.
